3. Setup and Installation

The AZIJYV P4 offers flexible installation options to suit various vehicle dashboards.

3.1 Choosing an Installation Method

The device comes with a split bracket that allows for 360-degree rotation, enabling adjustment of the viewing angle and height for optimal visibility.

Figure 3.1: Various installation positions and bracket adjustments.

3.2 Connecting the Device

The P4 supports both OBD and GPS power supply methods. Choose the appropriate connection based on your vehicle's compatibility.

1. OBD Connection (Recommended for compatible vehicles):

   Locate your vehicle's OBD-II port, typically found under the dashboard on the driver's side. Connect the provided OBD cable to the P4 host unit and then to the vehicle's OBD-II port. The device will draw power and data directly from the vehicle's system.

2. USB Connection (For GPS mode or incompatible OBD systems):

   If your vehicle is a diesel, manufactured before 2009, or if the OBD system is not compatible, use the provided USB cable. Connect one end to the P4 host unit and the other end to a USB power source in your vehicle (e.g., a USB car charger or a vehicle's USB port). This will power the device for GPS mode operation.

Once connected, place the P4 display on your dashboard using the non-slip mat and adjust the bracket for optimal viewing.

4. Operating Instructions

The P4 display features intuitive controls and a customizable interface.

4.1 Power On/Off and Initial Boot

The device will automatically power on when the vehicle's ignition is turned on (if connected via OBD) or when USB power is supplied. It will power off automatically when the vehicle is turned off or USB power is removed.

4.2 Interface Navigation and Customization

The P4 offers multiple interface themes and customizable settings. Use the sensitive touch buttons on the device to navigate through menus and adjust settings.

Figure 4.1: Examples of different interface themes and data displays.

• Switching Interfaces: Refer to the on-screen prompts or the detailed manual for specific button presses to cycle through available display interfaces.
• Ambient Light: The colorful ambient light can be customized. Consult the settings menu to change colors or turn the feature on/off.
• Vehicle Logo: You can set a custom vehicle logo to display on the screen. This feature supports many mainstream car models.
• Language Settings: The device supports multiple languages. Navigate to the system settings to change the display language.

4.3 Understanding Displayed Data

The P4 can display a wide range of vehicle data depending on the selected mode (OBD or GPS) and vehicle compatibility.

Figure 4.3: Overview of all available data points, including OBD speed, RPM, water temperature, voltage, oil temperature, turbo pressure, fuel consumption, and more.

• OBD Mode Data: Accesses data directly from your vehicle's ECU, including RPM, water temperature, voltage, fuel consumption, and specific vehicle parameters like oil temperature and transmission oil temperature for compatible models.
• GPS Mode Data: Primarily displays speed, altitude, driving time, mileage, and compass information using satellite positioning.
• Inclinometer/Slope Meter: Provides real-time pitch and roll angles of your vehicle, useful for off-road driving.
• Accelerometer: Displays G-values for acceleration and deceleration, offering insights into driving performance.

4.4 Alarm Functions

The P4 is equipped with various alarm functions to enhance driving safety. When an alarm condition is met, a pop-up window will appear on the display, accompanied by an audible prompt.

Figure 4.6: Example of an overspeed alarm pop-up and a list of supported alarm types.

• Overspeed Alarm: Alerts you when your vehicle exceeds a preset speed limit.
• RPM Alarm: Notifies you if engine RPM goes beyond a safe threshold.
• Water Temperature Alarm: Warns of engine overheating.
• Voltage Alarm: Indicates abnormal vehicle battery voltage.
• Fatigue Driving Reminder: Prompts you to take a break after continuous driving for a set duration (e.g., 4 hours).
• Additional alarms include oil pressure, oil temperature, exhaust temperature, turbo pressure, and tilt alarms.

5. Maintenance and Care

To ensure the longevity and optimal performance of your AZIJYV P4 display, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the display screen and exterior. Avoid abrasive cleaners, solvents, or spray directly onto the device.
• Temperature: Do not expose the device to extreme temperatures (hot or cold) for extended periods, as this may affect its performance and lifespan.
• Storage: If storing the device for a long time, disconnect it from power and keep it in a cool, dry place.
• Handling: Handle the device with care. Avoid dropping it or subjecting it to strong impacts.

6. Troubleshooting

This section addresses common issues you might encounter with your AZIJYV P4 display.

6.1 No Display/No Power

• Check Connection: Ensure the OBD cable or USB cable is securely connected to both the device and the vehicle's port/power source.
• Vehicle Ignition: If using OBD mode, ensure the vehicle's ignition is on.
• USB Power Source: If using USB, try a different USB port or car charger to rule out a faulty power source.

6.2 Inaccurate Speed/Data

• GPS Signal: In GPS mode, ensure the device has a clear view of the sky for satellite acquisition. Parking in an open area can help.
• OBD Compatibility: If in OBD mode, verify your vehicle is compatible (gasoline vehicle manufactured after 2009). If not, switch to GPS mode.
• Unit Settings: Check if the speed unit (KM/H or MPH) is correctly set in the device's settings.
• Calibration: Some parameters might require calibration. Refer to the detailed manual for specific calibration procedures if available.

6.3 Alarms Triggering Incorrectly

• Alarm Thresholds: Review and adjust the alarm thresholds (e.g., overspeed limit, RPM limit) in the device settings.
• Sensor Readings: If an alarm (e.g., water temperature, voltage) seems to trigger without a real issue, consult a professional mechanic to check your vehicle's sensors.

6.4 Display Not Clear/Too Bright/Too Dim

• Brightness Settings: Adjust the display brightness in the device's settings. The device has a photosensitive hole for automatic brightness adjustment; ensure it is not obstructed.
• Screen Cleanliness: Clean the screen with a soft, dry cloth to remove dust or smudges.
